[0029] Among them, the driving disk 7 is rotationally connected to the outside of the mounting seat 4. The bottom end of the sliding rod 9 is fixedly connected to the top of the sector gear 10. One end of the sliding rod 9 away from the sector gear 10 is fixedly connected to a limiting seat 14. The toothed rod 11 is slidably connected to the outside of the mounting seat 4. Two guiding seats 13 adapted to the toothed rod 11 are fixedly installed on the outside of the mounting seat 4.

[0031] When this embodiment is in use, when the dual-axis motor 6 is started, the driving disk 7 starts to rotate, so that the sliding rod 9 will make a reciprocating motion as the driving disk 7 rotates. The sliding rod 9 drives the sector gear 10 to swing reciprocally, and the sector gear 10 drives the toothed rod 11 to make a linear reciprocating motion, driving the baffles 12 at both ends to slide inside the feed hopper 2, realizing the precise quantitative feeding of Chinese and Western medicine ingredients and grains, ensuring that the addition amounts of each ingredient are accurate and error-free, and ensuring the accuracy of the ratio.

[0034] Please refer to Figure 5 , in this embodiment, a blanking mechanism for blanking the mixed Chinese and Western medicine ingredients and grains is arranged inside the preparation tank 1. The blanking mechanism includes a blanking plate 19 hinged to the inner wall of the preparation tank 1. An electric push rod 20 is hinged to the inner wall of the preparation tank 1, and the output end of the electric push rod 20 is hinged to the lower surface of the blanking plate 19.

[0035] Among them, one side of the blanking plate 19 away from the preparation tank 1 extends into the inside of the partition plate 3. A blanking port adapted to the blanking plate 19 is opened in the inside of the partition plate 3, and the blanking plate 19 is swingably connected to the inside of the blanking port.

[0036] Please refer to Figure 5, in this embodiment, a pushing mechanism for pushing the mixed Chinese and Western medicine components and grains is further arranged inside the preparation box 1. The pushing mechanism includes a fixed seat 21 fixedly connected to the inner bottom wall of the preparation box 1 and a transverse plate 24 arranged inside the preparation box 1. A pushing cylinder 22 is fixedly installed outside the fixed seat 21, and a pushing plate 23 is fixedly connected to the output end of the pushing cylinder 22.

[0037] When this embodiment is in use, when it is necessary to discharge the mixed Chinese and Western medicine compound grains, the pushing cylinder 22 is started, and its output end pushes the pushing plate 23 to move along the upper surface of the transverse plate 24. The pushing plate 23 pushes the Chinese and Western medicine compound grains out of the preparation box 1 to the discharge port and discharges them outside the device through the discharge port. The baffle hinged outside the discharge port can be closed when not discharging.

[0038] Among them, the transverse plate 24 is fixedly connected between the partition plate 3 and the left side wall of the preparation box 1.

A discharge port adapted to the pushing plate 23 is opened outside the preparation box 1, and a baffle is hinged outside the discharge port.

[0039] Please refer to Figure 5 , in this embodiment, a spraying device for coating the mixed Chinese and Western medicine compound grains is arranged on the upper surface of the preparation box 1 and extends into its interior. The spraying device includes a liquid storage tank 25 and a booster pump 26 fixedly installed on one side of the top of the preparation box 1. An installation pipe 27 is fixedly installed inside the preparation box 1 through a connecting frame. A number of spray heads 28 are fixedly communicated with the bottom of the installation pipe 27. A delivery pipe 29 is fixedly communicated between the output end of the booster pump 26 and the installation pipe 27, and an extraction pipe 30 is fixedly communicated between the input end of the booster pump 26 and the liquid storage tank 25. When the mixed Chinese and Western medicine compound grains need to be coated, the booster pump 26 is started, and the coating material is extracted from the liquid storage tank 25 through the extraction pipe 30. After the coating material is pressurized by the booster pump 26, it is transported to the installation pipe 27 through the delivery pipe 29 and then evenly sprayed on the mixed Chinese and Western medicine compound grains by the spray heads 28.

[0040] The working principle of the above embodiment is:

[0041] In use, the two feed hoppers 2 are respectively connected to the Chinese and Western medicine ingredient and grain feed pipelines. The double-shaft motor 6 is started through the controller, causing the moving seat 8 to perform a circular motion driven by the driving disc 7. However, due to the limitation of the slide rod 9, the driving sector gear 10 performs a reciprocating swing. The sector gear 10 meshes with the rack 11, and the rack 11 performs a linear reciprocating motion, causing the baffles 12 at both ends to slide inside the feed hopper 2 along with the rack 11, thereby controlling the feeding amounts of the Chinese and Western medicine ingredients and the grain. After the mixing is completed, the electric push rod 20 is started, and its output end pushes or pulls the blanking plate 19, causing the blanking plate 19 to swing around the hinge point. When the blanking plate 19 swings to a proper position, the mixed Chinese and Western medicine ingredients and grain slide down through the blanking plate 19 to the blanking port of the partition plate 3, and then enter the subsequent processing process. When the mixed Chinese and Western medicine compound grain needs to be coated, the booster pump 26 is started, and the coating material is extracted from the liquid storage tank 25 through the extraction pipe 30. After being pressurized by the booster pump 26, the coating material is transported through the delivery pipe 29 to the installation pipe 27, and then evenly sprayed on the mixed Chinese and Western medicine compound grain by the spray head 28 to form a coating layer. When it is necessary to discharge the mixed Chinese and Western medicine compound grain, the pushing cylinder 22 is started, and its output end pushes the push plate 23 to move along the upper surface of the cross plate 24. The push plate 23 pushes the Chinese and Western medicine compound grain out of the preparation box 1 to the discharge port and discharges it outside the device through the discharge port.

[0042] The installation methods, connection methods or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can realize the control of the electrical components through simple programming, and the existing publicly disclosed power connection technology also belongs to the common knowledge in this field. Therefore, the specific structural composition and working principle are not elaborated too much in this embodiment.
